Senring Electronics Co., Limited ,founded in 1998,is a worldwide designer, manufacturer of slip rings and rotary joints integrating research, testing, production and sales. We establishes long-term business relations with some Top 500 global companies and develop&provide them customized slip rings solutions as well as technical support.

As leading of manufacturer of carbon brush slip ring in domestic, Senring provides low cost conductive slip ring of solutions. we reseached 2 rings,3 rings, 4 rings and more series of carbon brush slip ring.

The traditional carbon brush and commutator collector ring are used together to
realize the mechanical commutation, to ensure that the input to the DC motor
output power as DC . With the development of power electronic technology,
brushless DC motor using electronic devices have begun to widely used. Other
motors (induction motor and synchronous motor) for AC motor, no brush structure.
Brush can only exist in the DC motor. The slip ring used connected with a
current between two objects relative movement. The most common is the motor
commutator, also has the linear motion of the car, motor car of brush

Carbon brush Description：

Carbon Brush is a device or signal transfer energy between the motor or
generator or other rotating machinery of the fixed part and the rotating part,
it is generally made of pure carbon coagulant, appearance generally is square,
hold in the metal stent, which has a spring pressed it on a rotating shaft, such
as oil drilling is completed and need to be test, it is through the brush to
convert signals from the rotating part (cable drum outsourcing wire) to the
ground instrument. Brush looks llike eraser, there is lead wire on top, The
Volume size can be customized as per request.

Brush holder is the role of the spring pressure on carbon brush collector ring
sliding surface in contact with the commutator or, the stable conduction between
the fixed body and the rotary body current. The motor carbon brush, brush holder
and is an important component of motor. when brush holder is not appropriate, it
will not have good characteristics , also effect the performance and working
life
